Russ,

  My postfix installation included a daily report mailed to postmaster by
root. It has all sorts of neat stuff.

  I think that I have finally figured out that the deferrals are outgoing
messages, not incoming. I get a lot of 'em, too. If these spam factories
cannot be annoyed by receiving bounced/rejected messages they sent to us,
then I would change the action from REJECT to IGNORE. According to
/etc/postfix/main.cf, 

# IGNORE the header line is silently discarded.

which I interpret to mean that the message is slipped into /dev/null. If I'm
wrong, then I, too, would like to know how to just throw away the rejections
that are not received by the sender so I can save the bandwidth.
